Red Bull RB9 - vented nose 13 March 2013

Red Bull technical chief Adrian Newey has followed Sauber's lead by introducing this twin-duct concept to the RB9's nose section. Air is sucked from the high-pressure area underneath the chassis into a duct (red arrow). The air then travels through the chassis (inset, right) via an s-shaped duct before exiting out of a hole on the top of the chassis (inset, left). The increased airflow on the top surface of the car helps to keep the airflow coming off the front wing 'attached' and thus improves airflow further back along the chassis's surface.
